AI doc generator quietly invented a net-30 clause nobody agreed to

The author builds automations for small teams and recently shipped an AI document generator for an agency: an intake form feeds details to an LLM, which fills a template and outputs formatted SOWs and contracts. About three weeks in, a client flagged a payment term nobody had agreed to — the model had added a net-30 clause simply because most SOWs it had seen contained one.
The scary part: a wrong number on a dashboard looks wrong, but a fabricated clause in a contract reads exactly like a real one — fluency is the problem.
Fix: the LLM no longer writes legal or numeric sections at all; those are slotted directly from the intake form. The model only handles descriptive wording, and every output is diffed against the template so any sentence not traceable to an input gets flagged before the doc ships. Lesson: for documents carrying obligations, money, or dates, the model should assemble, not author.
